Abstract
Apparatus is provided featuring a signal processor or processing module configured to receive signaling containing information about a pump no flow idle (NFI) state when the pump is running at a pump idle speed; and determine corresponding signaling containing information about whether the pump should remain in a no flow shutdown (NFSD) state or the pump NFI state, based upon the signaling received. The signal processor or processing module is configured to provide the corresponding signaling containing information about whether the pump should remain in the NFSD state or the NFI state.
